We've got the 99% purity confirmed on the HPLC form latest batches we're shiping, and that's pharmaceutical grade materail—basically the tightest tolerance you'll find for a GLP-1 receptor agonist peptide like this one.

The molecular weight comes in at 4113.57754 g/mol, which is what you'd expect for the C187H291N45O59 structure, and it's a in 10mg vials that we usually keep at -20°C for stability.

It's for research use only, so don't even think about anything else with this—our COAs are solid but our company can't speak to clinical appliction, and most buyers go with the 10mg vials for their dose-response work.
We've got bulk orders going out regularly, but check lead time on that since stock fluctuates (usually 2-4 weeks depending on batch size), and the MOQ for direct supply is typically 50 vials or so.

Actually, one thing that's not great for this is long-term storage at room temp—it degrades noticeably faster, so keep it frozen unless you're reconstituting within a day or two.

Also, we include the SDS and TDS with every shipment, and the HPLC data is availble per batch if you ask for it—something you'd want to verify anyway for the 99% purity claim.
We typically require a minimum order of 10 vials per batch. If you need less, just reach out and we can check availability for smaller quantities.
Yes, every batch comes with a full CoA showing the 99% purity result, along with HPLC and mass spec data. Just request it with your order.
Standard air freight to the UK takes about 5-7 business days after your order is processed. For rush orders, we can arrange express delivery in 2-3 days.
We currently stock only 10mg/vial for this product, but if you need a custom pack size, we can discuss a bulk repackaging arrangement for larger orders.
We ship with dry ice and insulated packaging to keep the powder at -20°C throughout transit. Just transfer it to a -20°C freezer immediately upon arrival.
